.TH BUFSPLIT 3GEN "Dec 29, 1996"
.SH NAME
bufsplit \- split buffer into fields
.SH SYNOPSIS
.LP
.nf
cc [ \fIflag\fR ... ] \fIfile\fR ... \fB-lgen\fR [ \fIlibrary\fR ... ]
#include <libgen.h>

\fBsize_t\fR \fBbufsplit\fR(\fBchar *\fR\fIbuf\fR, \fBsize_t\fR \fIn\fR, \fBchar **\fR\fIa\fR);
.fi

.SH DESCRIPTION
.sp
.LP
\fBbufsplit()\fR examines the buffer, \fIbuf\fR, and assigns values to the
pointer array, \fIa\fR, so that the pointers point to the first \fIn\fR fields
in \fIbuf\fR that are delimited by \fBTABs\fR or  \fBNEWLINEs.\fR
.sp
.LP
To change the characters used to separate fields, call \fBbufsplit()\fR with
\fIbuf\fR pointing to the string of characters, and \fIn\fR and \fIa\fR set to
zero.  For example, to use colon (\|:\|), period (\|.\|), and  comma (\|,\|),
as separators along with \fBTAB\fR and \fBNEWLINE:\fR
.sp
.LP
\fBbufsplit (":.,\et\en", 0, (char**)0 );\fR
.SH RETURN VALUES
.sp
.LP
The number of fields assigned in the array \fIa\fR. If \fIbuf\fR is zero, the
return value is zero and the array is unchanged.  Otherwise the value is  at
least one.  The remainder of the elements in the array are assigned the address
of the null byte at the end of the buffer.
.SH EXAMPLES
.LP
\fBExample 1 \fRExample of \fBbufsplit()\fR function.
.sp
.in +2
.nf
/*
 * set a[0] = "This", a[1] = "is", a[2] = "a",
 * a[3] = "test"
 */
bufsplit("This\etis\eta\ettest\en", 4, a);
.fi
.in -2

.SH NOTES
.sp
.LP
\fBbufsplit()\fR changes the delimiters to null bytes in \fIbuf\fR.

.LP
When compiling multithreaded applications, the \fB_REENTRANT\fR flag must be
defined on the compile line.  This flag should only be used in multithreaded
applications.
